Soil stays saturated along a defined corridor
A perforated collection trench may intercept moisture moving through the soil beside a lawn, planting bed, retaining area or foundation-side zone.
The collection method must match the water
A French drain is not the answer to every puddle
Surface water and subsurface water behave differently. A trench designed to relieve saturated soil should not be substituted for corrective grading, surface basins or a dedicated roof-water line when those methods address the actual condition more directly.
Visible runoff collects in a surface depression
A low area may require elevation correction, a catch basin or both. Hiding the low spot beneath gravel does not establish positive surface flow.
Downspouts release concentrated roof runoff
Roof water is normally connected to solid conveyance pipe. It should not be intentionally discharged into the perforated French-drain trench.
Field diagnosis before excavation
Match the symptom to the construction response
Residential installation sequence
Build the route before closing the trench
The exact components and dimensions are defined after the property is evaluated. The construction order keeps critical elevations visible until the system is ready for restoration.

The buried system depends on visible installation control
Tomball residential conditions
Clay soil and limited fall require an outlet-first plan
Tomball properties can include compacted clay, broad lawns, narrow side passages, large roof areas and limited elevation change between the wet area and the street or ditch. A French drain cannot move water uphill by itself. The proposed trench must connect to a viable gravity outlet or be coordinated with another conveyance method.
The estimate is based on measured route length, access, excavation, spoil removal, aggregate quantities, pipe and fittings, outlet construction, irrigation conflicts and surface restoration.

French drain planning questions
What homeowners should know before installation
How is a French drain different from a catch basin?
A French drain intercepts water within saturated soil along a trench. A catch basin collects visible surface runoff at a defined low point. The two systems may serve different areas of the same property.
Can downspouts connect directly to the perforated pipe?
Concentrated roof runoff is normally carried in solid pipe rather than released into a perforated trench. Both systems can be coordinated while preserving their separate collection functions.
Where does the collected water go?
The route must terminate at a responsible outlet supported by property elevations and applicable requirements. The discharge point is evaluated before the trench alignment is finalized.
Will a French drain correct an incorrectly graded lawn?
Not automatically. Surface depressions and reverse slopes may require grade correction. A French drain addresses subsurface saturation, so both methods may be necessary when both conditions exist.
What happens to irrigation lines in the trench route?
Known utilities should be marked before excavation, and irrigation conflicts are reviewed onsite. Necessary repairs or adjustments should be defined in the project scope.
How is the installation price determined?
Pricing depends on access, trench length and depth, excavation conditions, aggregate volume, pipe, fittings, outlet work, disposal, irrigation conflicts and the required surface restoration.
Schedule an onsite drainage review
Start with the wet soil, trench route and discharge elevation
PLS Landscaping will review the recurring wet area, surface grade, foundation clearance, downspouts, access, irrigation and outlet options before preparing a French-drain construction scope.
